V HENRY 'o'. ALBRECHT," or Tartan HAUTE," INDIANA;

To all whom it mayco nccm: I I

a citizen of the United States, residingat Terre Haute in the county ofVigo and State of Indiana, have invented a new and usefulHydrocarbon-Lamp, of which the following is a specification.

The present invention appertains to hydrocarbon lamps, and aims toprovide a novel and improved vapor lamp.

It is the object of the invention to provide a hydrocarbon lamp havinganovel assemblage of the component parts, and improved generally in itsconstruction and details, to enhance theutility and efficiency thereof,the structure having novel means for generating the gasolene or othervapor, and the device also being comparatively simple and inexpensive inconstruction.

With the foregoing and other objects in viewwhich will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the detailsof construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made Within thescope of what is claimed, with out departing from the spirit of theinvention. a

The invention is illustrated in the accompanying drawing, wherein Figure1 is a side elevation of the lamp, portions-being broken away. Fig. 2 isa vertical section taken on the line 22 of Fig. 1. Fig. 3 is a frontelevation ofthe primer for starting the lamp.

In carrying out the invention, there is provided a vertical pipe ortubular mem her 1 threadedly engaged to a suitable controlling valve 2and threadedly engaged at,

its upper end in the threaded bore of a horizontal coupling 4. The bore3 is arranged vertically, and the coupling 41 projects to one side fromthe pipe 1. The pipe 1 has a central rod or wire 5 therein, and asbestosor similar packing 6 around the rod or wire 5. A vertical pipe ortubular member 7 is arranged above the lower pipe 1 and in alinementtherewith and has its lower end threadedly engaged into the bore 3 andprojects upwardly from the coupling 4:, the upper end of the pipe 7being closed by a removable cap 8 threaded thereon.

Disposed axially within the pipe 7 is a Be it known that I, IIENRYCALisniioirr,

vertical tube" 9 of. smaller diameter than the pipe 7, having'its upperend terminating short of or spaced from the cap 8 or. the upper end ofthe pipe 7, while, the lower end of the tube 9 has an enlarged portion10 threadedly or otherwise engaged into the upper end of the pipe 1. Thelower end of the tube 9 is thus in communication with the pipe 1, whilethe upper end of the said tube is-in communication with the upper end ofthe pipe 7, the enlarged portion or plug 10 providing a closure orbarrier between the'adjacent ends of the pipes 1 and 7. An asbestos orequivalent packing 11 is disposed within the pipe 7 around the tube 9.The tube 9 as well as the pipes 1 and 7 and coupling 4: are constructedof suitable metal. v

The coupling 1 is provided adjacent that end remote from the pipes 1 and7 with an upper socket 12, and the coupling has a duct12 between thesocket 12 and bore. 3, this duct 12 communicating with the bore 3between the adjacent ends of the pipes 1 and 7, so that the said duct isin communication with the lower end of the pipe 7. A nozzle or nipple 13is threadedly engaged into the socket 12 so as to project upwardly fromthe coupling, and is provided with a restricted outlet duct 14: for thevapor, the free end of the nozzle or nipple 13 being tapered. An airchamber or casing 15 is provided at its lower end with an aperture 16receiving the tip of the nozzle 13, and the chamber 15 is provided atthat side remote from the pipe 7 with a depending tubular air inlet 17projecting downwardly past the free end of the coupling 4.

The lower end of a mixing tube 18 is threadedly engaged to the upper endof: the chamber 15 in alinement with the nozzle 13 to receive the jet ofvapor discharged from said nozzle, and the upper end of the mixing tube18 threadedly engages the intermediate portion 20 of an inverted U-shaped head 21 which is hollow, and which has its limbs arranged atopposite sides of the pipe 7 in a depending position. The mantles 22 areapplied to the ends of the head 21 at the opposite sides of the pipe 7to receive the vapor from the head.

In starting the lamp, a priming torch is employed, this torch embodyinga wire or stem 2 1 having an asbestos or equivalent wick 25 embracingthe same. The stem or shank 24 is provided at its opposite ends with ahook 26 and finger ring 27 respectively, and a coiled Wire 28v hasitsends engaging the stem 24and embraces the wick 25 for holding it inplace on the stem. The

wick 25 is soaked with alcohol or other equivalent priming fuel, andwhen lighted;

ofthe pipe 1 and wire 5 and asbestos 6 contained thereon. The asbestos 6also serves to' strain the fuel. The vapor then passes upwardlythroughthe tube 9 into the upperen-d of the pipe 7, and then passes downwardlythrough the asbestos 11 within said pipe 7 t0 the lower end ofsaidpipe.The pipe 7 and parts contained thereby being heated, will serve tosuperheat the vapor, whereby a lighter and more effective vapor isobtained. The vapor passes from the lower end of the pipe 7 through theduct 12 into the socket 12 and thence is discharged through the duct 14:of the nozzle 13 through-the chamber 15 into the mixing tube 18, airbeing sucked or drawn into the chamber 15 by way of the air inlet 17,and the air is drawn into the tube 18 to be mixed with the vapor. Themixture is blown into the head 21 and from there into the mantles 22 tosupport the flames which heat the mantles to an incandescent state. Assoon as the-mantle flames appear, the torch can be removed, since theheat from the mantle flames willcontinue the generation of thevapor byheating the pipes 1 and 7 and the parts contained therein.

By the arrangement of the pipes 1 and 7 and tube 9, vapor is generatedin an effective manner, without a complicated generating device, and theappearanceand compactness of the lamp is improved since the generatorsimply embodies upon its exte- Gbpiesof this patent may be obtained torfive cents each, by: addressing. the GemmissionepofiPatents,

rior, the pipes l and 7 connected by the coupling 4.. The assemblage ofthe parts is also of" advantage, to promote compactness, simplicity andcheapness. The pipe 1 is capable of supporting the other parts of the,lamp and the coupling 4, chamber 15, mixing tube 18 and head 21 areassembled in a compact and 'desirable manner with the pipes 1 and 7. Theintermediate portion of the head 21 has an outstanding apertured car 23embracing the pipe 7. By sliding the head12l upwardly, the mixing tube18 and chamber 15 are lifted therewith ofiof the nozzle 13, whereby saidnozzle is readily accessible for purpose ofcleaning, repair-or Thevarious parts may bereplacement. readily assembled and taken apart.

The present appliancemay be used asa table lamp, as a lantern, as, achandelier lamp, or the like, and a suitable shade or globe and itsholder-may be employed asusual.

Having thus described the invention, What pipe, said coupling having aduct establishing communication between the respective end of the secondpipeand the nozzle,

an air chamber engaged to said nozzle, anupstanding mixing tube attachedto said chamber to receive the jet from the nozzle,

and a burner head attachedto said mix-ing tube and engaged to saidsecond pipe, said head being adapted to support a mantle at one side ofsaid second pipe.

In testimony that" I claim the foregoing as my own, I have heretoaffixed my signature in the presence of two witnesses. HENRY C.ALBRECHT. Witnesses:
